Table 1.

Characteristics of deaf and hearing participants tested: mean (s.d.) [range] of age, NVIQ (shortened version of Advanced Progressive Matrices - APM), reading level (Gates-McGinitie reading test) and education level. Deaf and hearing participants did not differ on NVIQ or education level (p’s >.1). However, hearing participants were younger and better readers than deaf participants (p’s<.005)*.

NB: see Table 3 for characteristics of participants included in the ERP analyses.

	Age* (months)	NVIQ (APM) (max=12)	Reading raw Score* (max=93)	Education level (max=7)
Deaf (n=15)	409 (129) [255-677]	7.1 (3.1) [3-12]	79.9 (11.8) [49-93]	5.9 (1.0) [4-7]
Hearing (n=15)	306 (97) [224-549]	7.6 (3.0) [3-11]	90.4 (1.5) [87-92]	5.6 (0.74) [5-7]
